ἐφάλλομαι

I leap upon

Definition

The verb ἐφάλλομαι means 'to leap upon' or 'to spring upon' with aggressive intent. In its single New Testament occurrence, it describes a sudden, violent physical assault, as seen in Acts 19:16 where the man possessed by an evil spirit leaps on the seven sons of Sceva and overpowers them. The word implies a forceful, overwhelming attack initiated by a sudden, dynamic movement. While it can be used in a purely physical sense, in the biblical context it carries connotations of a hostile, overpowering action.

Biblical Usage

This word is used only once in the New Testament, in Acts 19:16. It describes the action of a man controlled by an evil spirit who violently attacks the seven sons of Sceva. The usage is in a narrative context of a spiritual confrontation, highlighting the physical manifestation and superior power of the demonic spirit against those attempting to misuse the name of Jesus.

Etymology

ἐφάλλομαι is a compound verb from the preposition ἐπί (epi, meaning 'upon') and the verb ἅλλομαι (hallomai, meaning 'to leap, spring, or jump'). The combination literally means 'to leap upon.' It is a middle/passive deponent verb, indicating the subject acts upon themselves or for their own benefit in the action of leaping.

Semantic Range

This word is significant in illustrating the reality and danger of spiritual warfare. In Acts 19:13-16, the violent action described by ἐφάλλομαι demonstrates that unauthorized or hypocritical use of spiritual authority (like the sons of Sceva invoking Jesus' name without a relationship with Him) is powerless and dangerous against genuine demonic forces. It underscores the biblical theme that true spiritual authority comes only from Christ and a submitted life, not from incantations or formulas.

In the Greco-Roman world, stories of exorcisms and encounters with spirits were common. The violent, physical reaction described by this word would have been understood as a classic sign of a powerful, hostile spiritual entity asserting dominance. The scene confirms to the original audience the superior authority of Jesus's name when wielded by genuine believers (like Paul) versus the failed magical practices prevalent at the time.

ἐπιπίπτω (epipiptō, G1968) — to fall upon, often with less emphasis on the leaping motion and more on the resulting impact or embrace; προσπηδάω (prospēdaō, G4363) — to spring towards, a more general term for leaping forward without the inherent aggressive connotation of 'upon'.
